Some tourist traps are tons of fun. Estes Park is a nonstop carnival, with better food.
But I'm with you. I prefer to slow down and go beyond the crowds. The locals know the best places, and the experience is more authentic. That's why I want to go back to the British Isles. My high school trip was scheduled by others, and hit the highlights. It was a great start, but now I want to write my own itinerary.
